Market evolution: Polyether polyols (CN 390729) — 2015–2025

Introduction

This report examines the evolution of EU trade in Polyethers, in primary forms (CN 390729), a broad category encompassing polyethylene glycols, polyether alcohols, and other specialty polyethers. The product group sits within the broader plastics and polyesters value chain (Chapter 39) and serves as a critical input for polyurethane foams, coatings, adhesives, and numerous downstream applications in construction, automotive, and consumer goods. The available data window covers 2022–2025, a period shaped by post-pandemic normalization, the 2022 energy crisis in Europe, and shifting global supply dynamics. Over this period, the EU has remained a substantial net exporter of polyethers, though both export and import values have declined markedly—driven primarily by falling unit prices rather than a collapse in physical volumes.

1. Declining Trade Values Amid Price Normalization

The most striking feature of the 2022–2025 period is the pronounced decline in both export and import values, which masks a more nuanced story about volumes and prices. The overall trade picture reveals that value declines were steeper than quantity declines, pointing to a significant price correction after the elevated levels seen in 2022.

1.1 Export contraction was driven by price erosion more than volume loss

EU exports of polyethers fell from €2.01 billion in 2022 to €1.38 billion in 2025, a decline of 31.4%. Over the same period, export quantities decreased by 17.8%, from 635,698 tonnes to 522,845 tonnes. This means that roughly half of the value decline was attributable to falling unit prices rather than reduced trade volumes. The average export price dropped from €3,163/t to €2,639/t (−16.6%), reflecting a normalization from the elevated energy-driven pricing of 2022, when European chemical producers passed through record-high natural gas and feedstock costs.

1.2 Import values declined sharply despite stable volumes

On the import side, the EU saw import values fall from €1.24 billion to €883 million (−29.0%), yet import quantities actually edged up by 2.3%, from 329,968 tonnes to 337,679 tonnes. The entire value decline was therefore a price effect: the average import price collapsed from €3,768/t to €2,614/t (−30.6%). Notably, imports were priced above exports in 2022 (€3,768/t vs. €3,163/t), but by 2025 prices had converged (€2,614/t vs. €2,639/t), suggesting a more competitive global pricing environment.

1.3 The EU trade balance remained positive but compressed

The EU consistently maintained a trade surplus throughout the period, though it narrowed from €767 million in 2022 to €497 million in 2025 (−35.2%). This compression is partly structural: export volumes fell while import volumes held steady, and export prices declined less steeply than import prices, partially cushioning the surplus erosion. The net import reliance metric confirms this trajectory: the EU's net exporter position softened from −49.6% to −24.5% (where negative values indicate net exports). The minimum of −81.5% likely corresponds to an earlier year when the surplus was at its peak, and the current trend suggests the EU's competitive advantage in polyether production, while still substantial, is gradually narrowing.

2. Shifting Geographic Patterns in Trade Partners

The geographic composition of EU polyether trade evolved meaningfully between 2022 and 2025, with some traditional partners losing ground and others—most notably Brazil and Japan—gaining prominence. Partner-level data reveals distinct dynamics on the import and export sides.

2.1 Import sources consolidated around China while smaller suppliers retrenched

China remained the EU's largest single source of polyether imports throughout the period, though its share declined from €295 million to €235 million (−20.3%). The most dramatic contractions, however, occurred among secondary suppliers:

Saudi Arabia and Taiwan saw the steepest declines (−66.7% and −72.0% respectively), likely reflecting both the price correction from 2022 peaks and shifting production economics. Japan stands out as the only major supplier to have grown its exports to the EU (+10.6%), possibly benefiting from competitive pricing or product specialization. The concentration of imports by Herfindahl-Hirschman Index (HHI) rose by 10.4% in value terms (from 1,410 to 1,557), and by a striking 60.8% in volume terms (from 1,611 to 2,590), indicating that import volumes are increasingly concentrated among fewer suppliers—a trend that may raise supply-chain resilience concerns.

2.2 EU export destinations showed divergent trajectories

The top export partners reveal a mixed picture:

Most traditional partners saw declines broadly in line with the overall price correction. However, Brazil stands out with an 82.0% increase in EU polyether imports, rising from €38 million to €70 million. This likely reflects growing downstream demand in Brazil's construction and automotive sectors, or a strategic reorientation of Brazilian procurement toward European suppliers. Conversely, India saw the steepest decline (−48.9%), potentially indicating increasing domestic Indian production capacity or a shift toward Asian suppliers. Export concentration also increased (HHI from 699 to 777, +11.1%), though exports remain far less concentrated than imports, reflecting the EU's diversified customer base.

2.3 Trade volatility varied significantly across partners

The coefficient of variation (CV) analysis highlights which trade relationships were most unstable:

Most volatile import sources (by CV):

Most volatile export destinations (by CV):

The extremely high volatility of EU exports to the Russian Federation (CV of 1.16) is consistent with the geopolitical disruptions following Russia's invasion of Ukraine and the subsequent sanctions regime. Singapore and Thailand showed the highest import volatility, likely reflecting the small scale and episodic nature of these trade flows rather than structural instability. In contrast, core partners such as Switzerland (CV 0.02 on the export side) and the United Kingdom (CV 0.04) demonstrated remarkably stable trading relationships.

3. Production Realignment and Intra-EU Specialisation

Beyond trade flows, the market structure data reveals important developments in EU production and the specialization profiles of individual member states.

3.1 EU production volumes declined while values increased

EU domestic production of polyethers (reported in kilograms) fell from 1.76 billion kg to 1.64 billion kg (−7.2%), yet production value rose from €2.76 billion to €3.33 billion (+20.5%). This apparent paradox—declining volumes but rising values—is partly explained by the fact that production data covers a longer period than the trade window, and the value increase likely reflects the impact of elevated pricing in the earlier part of the period. The production volume trajectory shows a maximum of 2.33 billion kg at some point during the period, suggesting a peak followed by contraction—consistent with capacity rationalization or demand shifts.

3.2 Belgium and the Netherlands emerged as the EU's polyether export hubs

The specialisation analysis for 2025 reveals clear winners and losers in the intra-EU production landscape:

Belgium displays the highest Revealed Symmetric Comparative Advantage (RSCA of 0.501), meaning it is by far the most specialized EU member state in polyether exports relative to its overall export profile. The Netherlands follows closely, and together these two Benelux countries account for over half of EU polyether production volume. Germany, while the largest producer in absolute terms (22.4% of EU production), shows only a modest comparative advantage (RSCA of 0.028), reflecting its much broader chemical sector.

At the other end of the spectrum, Bulgaria, Ireland, and Estonia show negligible specialization (RSCA below −0.98), with minimal polyether production or exports.

3.3 The EU's growing trade openness coexists with reduced net-exporter strength

The trade intensity and vulnerability indicators reveal a nuanced picture of the EU's evolving position:

Trade intensity—the ratio of trade (imports + exports) to production—rose from 49.2% to 58.2%, indicating that the EU's polyether sector has become more integrated into global markets. Export propensity also increased modestly. However, the net import reliance moved sharply toward zero (from −49.6% to −24.5%), meaning that while the EU remains a net exporter, its surplus relative to production has eroded. This combination of rising trade openness with declining net-exporter strength suggests that the EU is increasingly both importing and exporting polyethers, with import growth (in volume terms) outpacing export growth—a potential signal of structural competition from Asian producers.

The concentration indices further reinforce the picture of increasing market consolidation: export HHI rose from 699 to 777 (+11.1% in value), and import HHI rose more sharply, especially in volume terms (+60.8%). This growing concentration on the import side warrants attention, as it may reduce the EU's supply diversification.

Conclusion

The EU polyether market (CN 390729) experienced a significant value correction between 2022 and 2025, with trade values declining by roughly 30% on both the import and export sides. Critically, this was predominantly a price phenomenon rather than a volume collapse: export volumes fell by 17.8% while import volumes were essentially flat. The price normalization from 2022's energy-crisis peaks brought export and import unit prices into convergence around €2,600/t by 2025.

Geographically, the EU's trade relationships are reshaping. China remains the dominant import source but with a reduced footprint, while secondary suppliers like Saudi Arabia and Taiwan have retrenched sharply. On the export side, Brazil has emerged as a high-growth destination, while India and China have contracted. Import concentration has increased substantially, raising potential supply-chain resilience concerns.

Within the EU, production is concentrated in Belgium, the Netherlands, and Germany, with Belgium displaying the strongest comparative advantage. The EU remains a net exporter of polyethers, but this position has weakened considerably: net import reliance moved from −49.6% to −24.5%, driven by stable import volumes against declining exports. Rising trade intensity suggests the sector is becoming more globally integrated, but the simultaneous erosion of the net-exporter surplus signals that European producers face intensifying competition from non-EU suppliers—particularly from Asia.

Looking ahead, the key questions for this market will be whether European producers can maintain competitiveness in a lower-price environment, whether import diversification improves, and whether the growing demand from emerging markets like Brazil can offset declines elsewhere.
